Though Buddhism originated in India, the Buddhists are a minority in the country now. Buddhism faced this predicament in the country of its birth not now, but long back when Vedic Hinduism had a resurgence during the early centuries of A.D. Buddhism found its acceptance in countries abroad, in the east especially, including China, and for several centuries it remained the largest religion followers-wise, until the Christianity stole a march over it during the later centuries of trade and massive religious conversions.
The followers of Jainism live in various parts of India. Jainism was very influential widely in India once, as was Buddhism. It has the status of a minority religion in India today.
